Title: Device for coupling video recorders to one another or to magnetic tape or film apparatuses
Inventor: SCHULZ JUERGEN
IPC: G11B27/024
Filed: 1984-06-06
Abstract: In order to couple video recorders to one another or to magnetic tape or film apparatuses, synchronising pulses are used on the tape, which are known as "CTL pulses" in the case of video recorders and so-called "auxiliary pulses", which pulses are produced in the video recorder or are drawn from the capstan drive. Although the position of these pulses can be erroneous with respect to the tape, because of the slip on the capstan, this error is, however, compensated for with every CTL pulse. The "CTL signal" and its unreliable reading in the case of low and high speed are interpolated using auxiliary pulses. Absolute synchronism is maintained even in the absence of CTL signals.

Title: Method and arrangement for presetting and acquiring data while transferring milk from different suppliers' containers into a collecting container
IPC: G06F17/40
Filed: 1984-11-03
Abstract: The invention relates to a method and an arrangement for presetting and acquiring data while transferring milk from different suppliers' containers into a collecting container. Acquisition of data relating to the milk is made more reliable overall by the invention. Tampering with or faulty operation of the acceptance system and the measuring system are displayed on the one hand and stored as data on the other. It is no longer necessary for the operator to input commands which depend on suppliers regarding the mode of operation of the control system of the acceptance system and the measuring system of the collecting container. These advantages are achieved inter alia in that preset data which are specific to a run and a supplier can be stored, invoked and displayed, such data which affects the mode of operation of the control system of the acceptance system and the measuring system automatically adjusting the control system. The arrangement for implementing the method makes provision for a device for presetting and acquiring data, which device has a control panel and a display, is independent of the collecting vehicle, can be connected to the control system in a plug-compatible and replaceable manner, can interact with the control system and can be connected to a central data processing unit, acquired data being transmitted to the latter or preset data being received from it, as required.
Patent DE-3440339-A1 (DE)
Title: Guitar with keys
Inventor: SCHMITZ WILLIAM
IPC: G10D3/16
Filed: 1984-11-05
Abstract: The invention relates to a guitar with keys, in which striking or plucking of the strings is no longer carried out by the fingers of one hand or by means of a single plectrum, but via individual keys, which are incorporated in the body of the guitar in a suitable position alongside the main bridge. The keys actuate via a mechanism individually removable striking devices, which grip the strings either from below or from above and execute a plucking movement. According to a second embodiment, actuation of the individual keys can also be transmitted to the striking devices by means of electromagnetism. The invention makes it possible to learn even the most complicated striking techniques very rapidly and also to play chords which are not possible using the conventional playing method. Novel sound effects can also be achieved by these means.

Title: Drive for automation devices on presses
Inventor: ZEIDLER ROLF DIPL ING
IPC: B21D43/05
Filed: 1985-02-18
Abstract: The invention relates to a drive for automation devices on presses, in particular feed and removal devices in automatic press lines. The aim is to reduce the cycle times involved in the processing of sheet-metal parts with a large drawing depth and a large width in the direction of transport. The object on which the invention is based is to make possible actuation of the automation devices independently of the press during the standstill phase of the press and at the same time to guarantee absolutely reliable enforced movements of the gripper arms out of the danger zone during the stroke of the ram. According to the invention, this is achieved by virtue of the fact that the input shaft (4) of the device is, in addition to the separate drive (6), connected to the press drive via an intermediate gearing (9) and that a coupling (8) is arranged in such a way between the input shaft (4) of the device and the intermediate gearing (9) that the drive of the device during each working cycle of the press complex is derived from the press drive during the stroke of the ram and is performed independently of the press drive, by the separate drive (6) of the automation device, during the other phases of the working cycle. <IMAGE>

Title: DC high-voltage generating device for an X-ray tube
Inventor: TSUCHIYA AKIRA
IPC: H05G1/32
Filed: 1985-07-02
Abstract: A three-phase bridge invertor (54) converts a low DC voltage into low three-phase AC voltages using series-resonant circuit arrangements. The latter are formed by capacitors (30A-30C) and primary windings (84A-84C) of a three-phase transformer (84). The three-phase transformer (84) transforms the low AC voltages on its secondary windings (84Y; 84Z), which are arranged in a star or delta circuit, into high AC voltages or AC high voltages. The high AC voltages which are induced in the secondary windings (84Y; 84Z) are rectified in order to supply a DC high voltage which is free of ripple and is suitable for an X-ray tube (90). <IMAGE>
Patent DE-3523955-A1 (DE)
Title: Vibrator unit
Inventor: ROSTOCK FRITZ PROF DR
IPC: B06B1/16
Filed: 1985-07-04
Abstract: The vibrator unit serves to transmit vibrations of differing frequencies and amplitudes to different objects, e.g. for industrial purposes, particularly for materials testing, failure investigation in buildings, for the purpose of establishing transportation damages, etc., and also for installation in road building machinery. In a vibrator unit according to the invention, the unbalance is provided as a liquid (F) which is continuously pumped by means of a pump (28) from a liquid reservoir (36) into a cavity (11), arranged eccentrically relative to the axis (2) of rotation, of a rotating flyball (7) and is flung back from there into the reservoir (36) as a consequence of the centrifugal force via a narrow outlet channel (13) - etc. If the pump (28) is switched off, the cavity (11) is emptied virtually instantaneously, and the vibrations immediately stop. However, the flyball (7) continues to rotate unaffected and is ready at any time to resume circulation of liquid. In all known vibrator units, after the drive machine was stopped the rotation of the flyball continued for minutes, and after the drive was switched on again it was almost just as long until the desired speed was achieved again. This decisive defect of the vibrators previously known has been overcome completely by the invention described here. It opens up novel perspectives for the use of vibrators. <IMAGE>
